[QUOTE="Fred Weinberg, post: 3111928, member: 86437"]Mis-annealed planchets can have copper colored, and actual thin copper 'plating' on the planchet, mostly seen on Nickels. This 1968 (old) Nickel was a thin layer of copper, probably from the buildup of copper pulled from the nickel planchet when it was annealed; that thin layer found it's way into the striking chamber (probably laying on, but not being bonded to) a normal nickel planchet. It was struck, and detached - that's why you see an incused Obv. on the reverse of this 'shell'. Very similar to what Paddyman98 posted.[/QUOTE]
